No, no bending the endlinks on the Uncle Seiko one. I did fit the Uncle Seiko bracelet back on my SARB033 and ordered another standard OEM jubilee from Aliexpress (Rolamy). It's fits similarly, although the clasp is even worse than the tin can clasp on the Uncle Seiko (but it's way cheaper though and you can actually buy it, since the Uncle Seiko one is sold out).
As you see the fit of the endlinks is quite good, while far from perfect. With a little bend you might get it even better, but it's fits fine and you don't notice the gap.
